This western Entoloma is fond of hardwoods, and can be recognized by its fairly large stature, the yellow-brown cap that does not develop a prominently lined margin, the finely lined white stem, and the mealy odor. Microscopic features (see below) will help confirm identification.

Description:

Ecology: Saprobic; growing alone, scattered, or gregariously under hardwoods (occasionally reported under conifers); summer and fall (and over winter in California); fairly widely distributed west of the Great Plains.

Cap: 5-9 cm; convex becoming broadly convex or broadly bell-shaped; dry to greasy; smooth; yellow-brown, fading with age; the margin not lined or only faintly lined at maturity.

Gills: Attached to the stem; nearly distant; at first white, becoming pink with maturity.

Stem: 7-20 cm long; 1-2.5 cm thick; more or less equal; dry; smooth but finely lined longitudinally; white, often discoloring and bruising brownish near the base.

Flesh: Thin; fragile; white.

Odor and Taste: Mealy.

Chemical Reactions: KOH on cap surface negative.

Spore Print: Pink.

Microscopic Features: Spores 7-12 x 5-12 µ; mostly 5- and 6-sided; angular; inamyloid. Cystidia absent. Pileipellis a cutis. Clamp connections present.

Rhodophyllus lividoalbus is a synonym.
